Ultimate Handyman | How to drill tungsten carbide @ultimatehandyman | Uploaded January 2019 | Updated October 2024, 6 days ago.
Tungsten carbide is one of the worlds toughest metals, it is impossible to drill using traditional drill bits. In this video a JCB diamond tech hole saw is used in order to drill through some 6mm or 1/4-inch-thick tungsten carbide. In a previous video I drilled out a snapped off HSS tap using one of these diamond coated hole saws, you can see that video here- youtube.com/watch?v=7JCfEMrCjhc
